Title:
BOARD FOR SIGNAL TRANSMISSION
Document Type and Number:
Japanese Patent JP2010011290
Kind Code:
A
Abstract:

To improve appearance of a board which can transmit a signal to a communication device placed in the vicinity of the board by using variation of an electromagnetic wave without degrading a communication performance.

The board has a waveguide layer 10 for transmitting the electromagnetic wave and can transmit the signal between the communication device placed in the vicinity of the board and the waveguide layer 10 by using variation of the electromagnetic wave. In the waveguide layer 10, a sheet-like insulator layer 13 is sandwiched between a first conductor layer 11 that is arranged in a front side, of a mesh sheet shape, and of metal and a second conductor layer 12 that is arranged in a rear side, of a sheet shape or a mesh sheet shape, and of metal. A coating layer 17 including a coloring agent is formed in the front side of the first conductor layer 11 so as to enable communication by the waveguide layer 10 and give appearance of gradation by suppressing luster of the first conductor layer 11. The first conductor layer 11 can be seen through the coating layer 17.
